Uranium sulfate U(SO4)2  is a water soluble salt of uranium. It is a very toxic compound and should not
be ingested. Uranium sulfate minerals commonly are widespread around uranium
bearing mine sites, where they usually form during the evaporation of acid
sulfate-rich mine tailings which have been leached by oxygen-bearing waters.
Uranium sulfate is a transitional compound in the production of Uranium
hexafluoride. It was also used to fuel aqueous Homogeneous Reactors.

Hazards and Protection.
Storage Keep in a cool, dry, dark location in a tightly sealed
container or cylinder. Keep away from incompatible materials, ignition
sources and untrained individuals. Secure and label area. Protect
containers/cylinders from physical damage.
Handling All chemicals should be considered hazardous. Avoid direct
physical contact. Use appropriate, approved safety equipment. Untrained
individuals should not handle this chemical or its container. Handling
should occur in a chemical fume hood.
Protection Wear appropriate protective gloves, clothing and goggles.
Respirators Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks Do not touch damaged packages or spilled material. Cover liquid spill
with sand, earth or other noncombustible absorbent material. Cover powder
spill with plastic sheet or tarp to minimize spreading. Contact radiation
safety officer.
Stability No data.
Fire.
Fire fighting Presence of radioactive material will not influence the fire
control processes and should not influence selection of techniques. Small
Fires: Dry chemical, carbon dioxide, water spray or regular foam. Large
Fires: Water spray, fog (flooding amounts).
Fire potential May burn but does not ignite readily.
Health.
Exposure effects
   Ingestion See Inhalation.
   Inhalation Minimal risk if packaging remains intact. Package damage can result in a
measurable release of radiation but the risk is still low.
   Skin See Inhalation.
   Eyes See Inhalation.

First aid    IngestionMedical problems take priority over radiological concerns. Use first aid
treatment according to the nature of the injury. Do not delay care and
transport of a seriously injured person.   InhalationApply artificial respiration if victim is not breathing. Administer
oxygen if breathing is difficult. See Ingestion.   SkinImmediately flush with running water for at least 20 minutes. See
Ingestion.   EyesImmediately flush with running water for at least 20 minutes. See
Ingestion.

Emergency and First Aid Procedures


Ingestion:

Medical problems take priority over radiological concerns. Use first aid
treatment according to the nature of the injury. Do not delay care and
transport of a seriously injured person.


Eyes:
Immediately flush with
running water for at least 20 minutes.


Skin:
Immediately flush with
running water for at least 20 minutes.


Inhalation:
Apply artificial respiration if victim is not breathing.

Administer oxygen if breathing is difficult.
